FULL PRODUCT VERSION :
windows:
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b18)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

linux:
java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26)
Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Windows 7 64bit, Java8u25
Xubuntu 64bit, Kernel 3.13.0-37-generic, Java8u20

A DESCRIPTION OF THE PROBLEM :
Using DecimalFormat with RoundingMode.HALF_UP doesn't round correct. On tie-breaking or above the digit isn't rounded up.

For example: When one digit in the fraction is needed I assume following values:
1.17 ~~ 1.2
1.19 ~~ 1.2
1.49 ~~ 1.5

These values could be produced by Java7 but not in Java8. This is really bad because RoundingMode HALF_UP is used for commercial rounding of almost all.

REGRESSION. Last worked in version 7u71

ADDITIONAL REGRESSION INFORMATION:
not ready to hand for windows

linux:
java version "1.7.0_02"
Java(TM) SE Runtime Environment (build 1.7.0_02-b13)
Java HotSpot(TM) 64-Bit Server VM (build 22.0-b10, mixed mode)


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Instantiate NumberFormatter
2. Set the rounding mode to HALF-UP
3. add fraction digits to round - don't round to whole digits
3. try to format values without zero as integer and without zero left of the rounding position

fe:
0.55 ~~ 0.6 << this works
1.55 ~~ 1.6 << this doesn't work, Java8 calculates 1.5


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
1.17d should be rounded to 1.2
1.55d should be rounded to 1.6
ACTUAL -
1.17 have been rounded to 1.1
1.55 have been rounded to 1.5

ERROR MESSAGES/STACK TRACES THAT OCCUR :
no error

REPRODUCIBILITY :
This bug can be reproduced always.
